My first batch of beer is currently in the fermenter. It has definetly begun fermenting as I have observed bubbling in the airlock as well as yeasty deposits on top. However, my beer is very cloudy and looks like apple cider. It has only been in the fermenter for three days but bubbling in the airlock has slowed down to once every minute. Is fermentation done and my beer is just foggy for some other reason, or should I give it more time?
